Low frequency bass test sine wave

Let's test your subwoofer low-frequency respond. Each frequency duration is 3 second long so you can here different clearly. Frequencies start from 1Hz to 300Hz.

You may not hear 1 -10 Hz sine wave frequencies because human hearing limitation but modern amplifier can amplify this low-frequency band, sometimes if you play these low-frequencies loud enough your body can feel it.

You also can not hear 11 - 19 Hz (some golden ears human may hear 18 - 19 Hz) but your room will be shaking if you play these frequencies band loud enough.

20 - 30 Hz frequencies range are audible if you have a big speaker, good headphone or subwoofer, a small speaker may not produce these low frequencies or sound decrease so much but you can feel it when you touch the speaker.

A good desktop external speaker low-frequency cut-off around 80 - 100 Hz but a normal laptop built-in loudspeakers low-frequency cut-off around 150 Hz.

Below video will come in handy when you work out side but forgot your gear or any person who don't own wave generator.

BEWARE: LOWER YOUR VOLUME AND SLOWLY INCREASE VOLUME OR YOUR LOVE SOUND SYSTEM DAMAGE!!!!!
